The current driver receive path allocates pages and stashes them into SKB fragments. This is not particularly useful as we don't support jumbo frames (which wouldn't be great with the small FIFOs on all the known implementations) anyway. It also makes us flush the caches and allocate more memory for RX than necessary. So set our RX buf to our max packet size instead (which we bump to 1536 bytes to account for packets with vlan tags etc...) like most other ethernet drivers. Then allocate skbs when populating the receive ring and DMA directly into them. This simplifies the RX path further.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
